HARO. J. COSTER, OF CHICAGO, ILLINOIS.

BOOKING-CHAIR.

Specification of Letters Patent No. 28,159, dated May 8, 1860.

To all whom 'it may concern:

Be it known that I, HARO. J. COSTER, of Chicago, in the county of Cook, in the State of Illinois, have invented a new and useful Improvement on Rocking-Chairs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification and to the letters of reference marked thereon,-Figures l and 4 being perspective views; Figs. 2, 3 and 6 vertical sections and Fig. 5 horizontal sec tion thereof.

The nature of my invention consists in adapting to the front part of the rockers of any common rocking chair Fig. l, the brackets a, a Fig. 4 joined by the piece 6, and allowed to turn on the axes CZ, CZ Figs. 4 and 3, and which are fixed to the rockers as shown in Fig. l, 2, 3. The brackets made of wood or any other appropriatesubstance are provided with rollers, c, 0, in order to prevent them from injuring the carpet or floor, and are further provided with a little catch e to hold them in the position as'shown in Figs. l and 2. The aXes, al, d, are provided at ac, Fig. 4, with a spring strong enough to bring the brackets down to the position, as in Fig. 3, where they are held by the bolts from going farther. The longer arm of the brackets must be of such a length that when the chair is nearly as far backward as possible, the rollers will bear on the floor when the brackets are in a perpendicular position, as shown in Fig. 3.

The use and mode of operation of the brackets are as follows: Whenever one wants the chair in the steady position as shown in Fig. 3, to rest or sleep, without being obliged to hold the chair in such a position with his feet, he presses on the catch e, when the brackets will come down and by throwing the chair backward they will assume the perpendicular position by means of the spring and keep the chair steady, the piece I), serving to rest the feet on; To reassume the ordinary position one has to throw the body a little backward and with the heel lift the brackets whenthe chair will come forward and the brackets may be replaced in the position as in Figs. 1 and 2. I further provide the rocking chair with an automat-ical fan consisting of the following parts: a square piece of wood or metal Gr Fig. 6, perforated so as to receive the rod F which can be lowered or raised and kept in the desired osition by the screw II. The upper part o the rod F is provided with the pulley K, and the piece W, which piece is perforated at J so as to receive the handle O of the fan N, which is held in place by screw L, see Figs. 1, 2, 3, 6. The pulley K, is provided with a spring M strong enough to bring the pulley and fan from the position in Fig. 3 to the position in Fig. 2. The rocker Y is further provided with an aperture as shown in Fig.

5, in which aperture is fixed a spring P, Figs. 2, 3, 5, strong enough to overcome the resistance of spring M of pulley K, and bring the fan in the position Fig. 3. The spring P is connected with the fan by a string or wire Z and which string runs over the pulleys, Gr, R, and K, the string consisting of two parts and connected by hook and eye y or any other means; the eye being fixed on the little peg V, when the fan is not used and the spring P held by it in the position as in Fig. 2. The spring P is fixed in such a place of the rocker, so that whenever the chair is in its center of gravity as in Fig 2, the spring is pressed inside by the weight of the chair and the person sitting on it. The fan may be placed on any part of the chair and the connection made accordingly.

The working of the above described fan is as follows: After being placed on the chair as in Fig. l, for which purpose the chair has a. square aperture to receive the piece G Fig. G. The chair being at rest and in its .center of gravity as in Fig. 9., the fan will have the position as in Fig. 2, but as soon as the chair is thrown backward the spring P becoming free to act will bring the fan down to the position Fig. 3, the chair coming forward again will press the spring P inside when the spring M will bring the fan again in an upright position as in Fig. 2, and so on, as long as the chair is rocking.

That I claim as my invention and desire to secure by Letters Patent is,-

Combining with a rocking chair a fan acting automatically by means of spring P in the rocker Y, cord Z, pulley K, spring M, rod F, all arranged substantially as and for the purpose specified.
